PET oxidative cyclization of silyl enol ethers carrying suitable side chains with olefinic double bonds results in the stereoselective formation of carbocycles. Two model compounds for investigating the influence of silyl enol ether ring size are synthesized. Furthermore the synthesis of a quasi-ste
Silyl enol ethers (2) react with trihutyl [(phenylthio) chloromethyl] stannane (1) in the presence of Zinc bromide to give B-phenylthiomethylstannyl ketones (3) in good yields. Silyl dienol ethers (4) mainly give products (5) due to y-attack, under these conditions. S-Stannyl Carbonyl compounds have
